Lift Terminology
Introduction:
Braun NL955 Millennium Series
lifts comply fully with the National
Highway Traffic Safety Adminis-
tration (NHTSA) specifications.
The Braun NL955 is consumer
oriented (designed to allow operation by the wheelchair passenger). NL955 lift models provide
fully automatic operation of all
lift functions as well as optional
automatic door operators (if so
equipped).
Lift models vary per platform size
(lift model numbers indicate lift
dimensions). A standard NL955
lift model is depicted in the Lift
Terminology Illustration. Refer to
the Lift Terminology Illustration
for identification of lift compo-
nents.
Lift operation procedures are
identical for all NL955 Series
lift models. The operating
instructions contained in this
manual and appearing on liftposted operating instructions
decals address the lift control
switches and the corresponding lift functions. Instructions
are provided for manual operation of the lift in event of power
or equipment failure.
Terminology: Become familiar
with the terminology that will be
used throughout this manual.
Become familiar with the identifi-
cation of lift components and their
functions. Contact your lift sales
representative or call The Braun
Corporation at 1-800-THE LIFT
if any of this information is not
fully understood.
Direction: The terms “left,”
“right,” “inboard,” and “outboard”
will be used throughout this
manual to indicate direction (as
viewed from outside the vehicle
looking directly at the lift). Refer
to the Lift Terminology Illustration
for clarification of direction terms.

Lift Terminology
Lift Components
Refer to the Lift Terminology Illustration on page 4.
Pump Module: The lift-mounted
pump module consists of the
hydraulic pump, the manual
hand pump, the electronic
control board and electrical
components that power the lift
electric/hydraulic systems. The
pump module is equipped with
three function-labeled control
switches.
Hand-held Pendant Control:
The hand-held attendant's pendant control is connected to the
pump module. The hand-held
pendant is equipped with four
push button switches, (UNFOLD,
FOLD, DOWN, and UP). The
momentary switches activate the
automatic lift functions. The lift
function labels illuminate to identify the function(s).
Lift Frame: The lift frame consists of the base plate, threshold
warning plate, towers, parallel
arms, vertical arms, platform
pivot arms and switch arm. Two
main hydraulic cylinders are
housed in the parallel arms.
The electrical/hydraulic powered
lift frame components mechanically unfold, lower, raise and fold
the lift platform assembly.
Switch Arm: An additional
UP/DOWN switch is provided on
the switch arm.
Platform Assembly: The platform assembly consists of the
steel tubing frame with grating
surface upon which the wheelchair is positioned, the outer
barrier, outer barrier latch, the
inboard locator, side entry and the
hydraulic cylinder assembly that
powers the outer barrier.
Lift-Tite
™
Latches: The spring-
loaded latches prevent the
platform from unfolding from the
stowed position in the event of
platform drift. Further details
regarding Lift-Tite™ latches are
provided on pages 18 and 19.
Outer Barrier: The cylinderpowered automatic outer barrier
provides a ramp for wheelchair
loading and unloading at ground
Page 6
Page 9
Lift Terminology
level. The NL955 platform is
equipped with a side entry that
allows boarding and exiting in
tight parking situations. The
outer barrier and side entry function together in unison.
Outer Barrier Latch: The
spring-loaded latch locks the
outer barrier in the vertical position when the platform raises
above ground level.
Inboard Locator: NL955 Series
lift models are equipped with an
automatic inboard locator that
also serves as the bridge plate.
The bridge plate bridges the gap
between the lift platform and the
vehicle floor. The inboard loca-
tor/bridge plate automatically rotates from the horizontal position
to the vertical position as the
lift lowers and raises. Further
details regarding the automatic
mechanical inboard locator are
provided on pages 18 and 19.
Vehicle and Lift Interlocks
Braun Corporation NL955
Series lifts comply fully with all
NHTSA vehicle and lift interlock
specifications. Vehicle move-
ment is prohibited unless the lift
door is closed, ensuring the lift
is stowed. The lift will not function unless the vehicle is parked
and secured.
The NL955 features an audible
threshold warning system that
will activate if the threshold area
is occupied when the platform
is one inch or more below floor
level.
The inboard locator and outer
barrier sense weight to prohibit
lift operation. The lift will not
function if the inboard locator or
the outer barrier are occupied.
The lift platform cannot be folded
(stowed) if occupied

Unfold: Unfold is the action
of the platform rotating out and
down from the fully-stowed
(vertical) position to floor level
(horizontal) position when the
UNFOLD switch is pressed.
B. DOWN - Platform Lower:
Down is the action of the platform
lowering from floor level position
to fully-lowered (ground level)
position when the DOWN switch
is pressed.
C. DOWN - Outer Barrier
Unfold (Deploy) - When the
platform reaches the fully-low-
ered (ground) position and the
DOWN switch is continued to be
pressed, the outer barrier rotates
downward from vertical position
to ramp position.
STOW (D-F)
D. UP - Outer Barrier Fold
(Raise): When the lift is fully
lowered and the outer barrier is
in the ramp position, pressing
the UP switch first rotates the
outer barrier upward from ramp
position to vertical position.
E. UP - Platform Raise: Up is
the action of the platform raising
from ground level to floor level
(fully-raised) position when the
UP switch is pressed.
F. FOLD (In) - Platform Fold:
Fold is the action of the platform
rotating up and in from the floor
level (horizontal) position to fullystowed (vertical) position when
the FOLD switch is pressed.
Stowed Position: The lift is
stowed when the lift platform has
been fully raised and folded fully
(vertical position).
Floor Level: Floor level is the
position (height) the platform assembly reaches in order for the
wheelchair passenger to enter
and exit the vehicle (fully raised).
The platform automatically stops
at floor level when unfolding from
the stowed position and when
raising from ground level.

are equipped with an automatic
inboard locator that also serves
as the bridge plate (inboard
locator photos below).
When the UNFOLD switch is
pressed and the platform unfolds
from stow position to floor level,
this mechanical locator/bridge
plate is automatically deployed to
the bridging (horizontal) position
to provide a bridge plate between
the platform and the lift base plate

The locator/bridge plate automatically folds (rotates) to the
vertical (roll stop) position when
the platform lowers to the ground
(DOWN switch is pressed). As
Page 20
Page 23
Operation Notes and Details
the UP switch is pressed and the
platform raises from ground level,
the inboard locator automatically
unfolds (rotates) to the horizontal (bridging) position when it
reaches vehicle floor level. The
bridge plate must overlap the lift
base plate a minimum 1/2".
When the FOLD switch is
pressed and the platform folds
from floor level to the stow (vertical) position, the bridge plate
automatically travels inboard to
the stowed position.
Interlock: The inboard locator
senses weight to prohibit lift operation if occupied.
Automatic Floor Level Switching: When the platform unfolds
from the stowed position, the platform stops automatically at floor
level when fully unfolded. When
raising the platform from ground
level, the platform automatically
stops at floor level when raised
fully.
Although the NL955 features
automatic floor level switching,
the lift operator (wheelchair passenger or attendant), must view
the platform to be certain the
platform is properly positioned at
vehicle floor level and the bridge
plate is properly positioned when
a passenger is entering or exiting
the vehicle. If the lift platform
does not automatically stop at
floor level as outlined,
discontinue lift operation immediately.
Outer Barrier and Side Entry:
The NL955 platform is equipped
with an outer barrier and a side
entry. See photos A, B and
C. The cylinder-powered outer
barrier and side entry provide a

the vertical position (UP switch
is activated to raise the platform
above ground level).
Note: The platform must raise
approximately three inches be-
fore the latch engages fully (see
photo C on page 22).
The latch disengages the barrier
when the platform lowers fully
(reaches ground level) and the
latch foot contacts the ground
(latch raises above the barrier).
The lift operator or attendant must
be certain the entire platform
reaches and rests safely on the
ground.

Page 26
Operation Notes and Details
Lift Features (continued):
Interlock: Lift platform move-
ment will be interrupted unless
the barrier is raised and the
outer barrier latch is positively
engaged.
Outer Barrier and Latch Operation: The lift operator must
activate the DOWN switch to
lower the platform fully to the
ground. The lift operator or attendant must view the platform
as it lowers to be certain the
entire platform reaches and
rests safely on the ground. Stop
activating the DOWN switch if
any portion of the platform is obstructed while descending or the
platform does not reach ground
level for any reason (contact
with an obstruction, mechanical
failure, exceeding the lift “floorto-ground” capacity, etc.).
After the platform is fully lowered
(platform reaches the ground),
the lift operator should continue
to press the DOWN switch to
unfold the outer barrier and the
side entry fully (ramp position).
Note: The outer barrier and side
entry must be fully unfolded
until the entire wheelchair has
crossed when loading or unloading at ground level. Discontin-
ue lift operation immediately
if the barrier or latch do not
operate properly.
Bridging: The NL955 incorpo-
rates a bridging feature. This
feature stops the down travel of
the platform if the outboard end
of the platform contacts a raised
surface (such as a curb), preventing the operator from lowering the
inboard end of the platform.
Switch Arm: The switch arm
automatically unfolds to the deployed position when the platform
unfolds and folds automatically
to the stowed position when the
platform folds. The passenger
may choose to grip the switch arm
when on the lift platform.
Note: The switch arm is equipped
with an UP/DOWN control switch
(page 16). Discontinue lift
operation immediately if the
switch arm does not operate
properly.

Operation Notes and Details
Lift Passengers
Do not attempt to load or unload a
passenger in a wheelchair or other
apparatus that does not fit on the
platform area. Do not exceed the
750 pound load capacity of the lift.
Passenger Orientation (Boarding Direction): The wheelchair
passenger must face outward
whenever on the platform.
The passenger must be positioned
in the center of the platform to
prevent side-to-side load imbalance. Other persons should not
ride on the platform with the
wheelchair passenger.
The wheelchair brakes must be
locked, the inboard locator and
the outer barrier must be in the
fully-up (vertical) position, and
the outer barrier latch must be
fully engaged whenever a
wheelchair passenger is on
the platform.
Do not use the outer barrier as
a brake. Stop and brake the
wheelchair when fully loaded
on the platform. Manually stop
and brake manual wheelchairs.
Stop powered wheelchairs with
the wheelchair controls. Turn
powered (electric) wheelchairs
off when on the platform.
Interlock: An audible threshold warning will activate if the
threshold area is occupied when
the platform is one inch or more
below the level. The threshold
warning plate identifies the
platform threshold area.
Vehicle (Floor Level) Loading
and Unloading: The platform
must be fully raised (at floor
level) and the bridge plate must
be properly positioned when
loading or unloading a passenger
in or out of the vehicle. Although
the NL955 features automatic
floor level switching, it is the
responsibility of the lift operator to ensure the platform and
the bridge plate are properly
positioned at floor level when
loading and unloading passengers.
If the outer barrier, inboard locator
or any other lift component does
not operate as outlined in this
manual, discontinue lift use im-
mediately and contact your sales
representative or call The Braun
®
Corporation at 1-800-THE LIFT

Support representatives will
direct you to an authorized
service technician who will
inspect your lift.
Position and secure
(buckle, engage,
fasten, etc.) the
wheelchair-equipped
occupant seat belt
before loading onto
the wheelchair lift
platform. Failure to
do so may result in
serious bodily injury
and/or property damage.
Wheelchair-Equipped Occupant Seat Belts
The Braun Corporation recommends wheelchair passengers
position and buckle their wheelchair-equipped seat belt (torso
restraint) as specified by the
manufacture before loading onto
a wheelchair lift.
Different types of disabilities
require different types of wheelchairs and different types of
wheelchair-equipped occupant
restraint belt systems (torso restraint). It is the responsibility of
the wheelchair passenger to have
his or her wheelchair equipped
with an occupant restraint (seat
belt) under the direction of their
health care professional.
Wheelchair lift attendants should
be instructed on any special
needs and/or procedures required
for safe transport of wheelchair
passengers.
Operation Procedure Review
The Braun Corporation recommends that the wheelchair lift
user and/or attendant review the
safety precautions and operation procedures appearing in this
manual and on lift-posted decals
with your wheelchair lift sales
representative, before attempt-
ing lift operation. Any questions
or concerns can be answered by
your sales representative at that
time.
Page 26

Operation Notes and Details
Using your own wheelchair,
operate the lift through all functions and enter and exit the
vehicle with the sales representative on hand to ensure the lift
is right for you as the end user
(applicable for your use based
on your physical abilities and the
physical characteristics of your
personal wheelchair). Become
familiar with the proper operation
of your lift before operating the
lift by yourself.
This lift operator’s manual must
be stored in the lift-mounted
manual storage pouch when
not in use.
Preventive Maintenance
Maintenance is necessary to
ensure safe and trouble-free lift
operation. Preventive lift maintenance consisting of careful
inspections of your lift system and
cleaning the lift should be a part
of your routine. Simple inspections can detect potential lift
operational problems.
Regular preventive maintenance
will reduce potential lift operation downtime and increase the
service life of the lift, as well as
enhancing safety.
During routine inspections, operate the lift through a minimum of
one complete cycle and note the
following:
• Do the automatic door(s) open
fully (if equipped)?
• Does the lift safely clear the
door(s) when unfolding and
folding?
• Do the lift control switches func-
tion properly?
• Do the automatic inboard loca-
tor and outer barrier operate
properly?
• Does the outer barrier latch
operate properly?
• Does the switch arm fuction
properly?
• Is the power source adequate or
weak?

Maintenance and Lubrication
W
A
RNING
Proper maintenance is necessary to ensure
safe, troublefree operation. Inspecting the lift for
any wear, damage or other abnormal conditions
should be a part of a regular service program.
Simple inspections can detect potential problems.
The maintenance and lubrication procedures
specified in the following schedule must be performed by a Braun authorized service representative at the scheduled intervals according to the
number of cycles.
NL Series lifts are equipped with hardened pins
and self-lubricating bushings to decrease wear,
provide smooth operation and extend the service life of the lift.
When servicing the lift at the recommended
intervals, inspection and lubrication procedures
specified in the previous sections should be
repeated. Clean the components and the surrounding area before applying lubricants.
LPS2 General Purpose Penetrating Oil is
recommended where
Light Oil is called out.
Use of improper lubricants can attract dirt
or other contaminants
which could result in
wear or damage to the
components. Platform
components exposed
to contaminants when
lowered to the ground
may require extra
attention.
Lift components requiring grease are lubricated
during assembly procedures. When these components are replaced, grease must be applied during
installation procedures. Specified lubricants are
available from The Braun Corporation (part numbers provided on page 44).
Maintenance and
lubrication procedures must be performed as specified
by an authorized
service technician.
Failure to do so may
result in serious
bodily injury and/or
property damage.
Page 43
Page 46
Maintenance and Lubrication
All listed inspection, lubrication and maintenance
procedures should be repeated at “750 cycle”
intervals following the scheduled “4500 Cycles”
maintenance. These intervals are a general
guideline for scheduling maintenance procedures
and will vary according to lift use and conditions.
Lifts exposed to severe conditions (weather,
environment, contamination, heavy usage, etc.)
may require inspection and maintenance procedures to be performed more often than specified.
Maintenance Indicator: The Lift Ready green
LED mounted on top of the pump cover will begin
to blink after every 750 cycles. The blinking LED
will not affect the functions of the lift, but is a
